A DELICATE BALANCE: Can Penny Fuller tempt Jack Davidson into the garden shed in Albee’s underrated follow-up to Who’s Afraid of Virginia Woolf?

A Delicate Balance is 40 years old now, but like the patrician clan at the frightened heart of it, the play has good bones. Edward Albee’s 1967 Pulitzer Prize winner, now getting a pitch-perfect revival from Merrimack Repertory Theatre (through April 6), was written on the cusp of the Summer of Love, in the wake of The Homecoming. Yet the old-fashioned three-act play starts off like upper-class drawing-room comedy, with wealthy Agnes and Tobias enjoying an after-dinner libation in their well-appointed parlor. Except that the subject of Agnes’s genteel chatter is the possibility that she might someday lose her mind, Somerset Maugham might be lurking. Even Agnes’s alcoholic sister Claire, blowing the dust off old hurts and rivalries, can’t quite spoil the cocktail party, over which Tobias presides like a country potentate. Neither can the likelihood that daughter Julia will soon be on their doorstep, fleeing a fourth failed marriage to batter at the bosom of her family, ruffle the suburban composure. But existential terror is about to start leaking into the air-conditioning, as long-time best friends and country-club cronies Harry and Edna show up unannounced. It seems they were having a quiet evening at home when they were overcome by a vague terror. “We couldn’t stay there, and so we came here,” Harry explains blandly. Will the hosts allow these “plague”-trailing intruders to poison their false comfort zone?

Despite winning the Pulitzer that Albee had been denied four years earlier for Who’s Afraid of Virginia Woolf?, A Delicate Balance has always seemed a David next to that Goliath of an allegorical marital meltdown, with its rough chemical peel of illusion. It’s only since its successful 1996 Broadway revival that the later and subtler work has started to glean the attention it deserves. A year ago, Trinity Repertory Company produced a well-acted revival that was nonetheless not so expertly cast and calibrated as this one, whose characters seem to have stepped right out of period and into The Twilight Zone. Even Penny Fuller’s bad-girl Claire, plinking devastating one-liners into her “willful” cups, is a bad girl of an era: an aging Sandra Dee, still trying to tempt Tobias or Harry into the garden shed for a reprise of their own sad, triangular, long-ago summer of love in the wake of devastating loss skimmed over and now part of the conversational wallpaper.

Despite being elegantly written, A Delicate Balance could as easily lurch in the direction of farce as toward poignancy and disturbance. Director Charles Towers brings all the roads together, so that even the over-the-top scene in which Julia — arrived home to find her passive-aggressive godparents invaders of what she had considered a private retreat — physically defends the cocktail cabinet is both hilarious and horrifying, so coltishly crazed is Gloria Biegler’s woman child betrayed. As Harry and Edna, Ross Bickell and Jill Tanner, the former stodgily bespectacled, the latter sporting a hairdo that is almost an auburn helmet, tiptoe across the line from dully harmless to menacing.

Perfect Balance Harold Pinter once said that his plays were about “the weasel under the cocktail cabinet.”

Basking in life Nancy and Charlie (Kate Braun and Peter Josephson) have made it to the other side: Their kids are raised, released into the world, and producing their own offspring.

Paint by numbers Edward Albee’s Three Tall Women are really one tall woman, and she’s a tall order.

Animal farm The word tragedy means “goat song” in ancient Greek, and indeed, the protagonist of Edward Albee’s The Goat or, Who Is Sylvia? is making beautiful music with a mistress of the caprine persuasion.

Origins of a species In her excellent theatrical pairing for Daniel Productions at the Players’ Ring, billed as 2 x 2 x 2 , director Liz Korabek juxtaposes two modern takes on the human quintessence.

Back to life Well, it was a close call, but now that we’ve crossed the Stygian flood of Christmas Carols and other holiday fiascos, we can get back to the business of theater that might occasionally surprise, scandalize, and even keep us breathing.
